I agree, and as you know I am a supplier. I have 510 only listed on my site as of now, because I currently have spme SLB parts left over still in stock on the 510 line (maybe 20% of the 510 line as I try to sell the stock off). I refuse to put "Genuine Joye" in referance to my 510 line until all of the SLB stuff is replaced in my inventory. As I phase out the rest of the SLB stuff. Id say 80% of my 510 line is all Genuine Joye now, but I still refuse to put up "Genuine Joye" till I sell of the rest of my SLB stock. Can be a real pain in the butt to put up all the extra products, just to list them one by one as they get phased out. But as a consumer I totally understand where you are coming from. When people ask me if my stuff is Genuine Joye or not, I tell them which attys, batteries ect have been changed over to them. I find it better that I do not hide anything, but people that know me around the forum know that about me. If a customer comes to me and asks "hey is this genuine joye?" I will tell them what colors have been replaced by genuine joye and these havent because I havent sold out of them yet. Hope that clears it up a little bit. May not adress why other suppliers don't do it (probably cause they don't sell Joye and don't care if you know or not), but at least I can atest to why I do.
